Product Details

The MAX14611 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the functionality of the MAX14611 quad bidirectional low-voltage logic-level translator in a 14-pin TDFN package. The highly configurable PCB enables direct evaluation of the IC through multiple jumper-selectable methods. Input power to the EV kit is provided by a Micro-USB, type-B connector, or by an external 5V power supply. On-board LDO regulators provide the appropriate voltage for each component, and potentiometers allow the user to independently adjust the power supply for either side of the level translator.
